Six months tops. Nothing more than an uneducated guess, and I'd like to see them hang around longer, but you cannot continue to hemorrhage money like that and stay in the game.
I watched the excitement generated on an almost daily basis at SlickDeals a month ago as it seemed like there was an OCZ SSD deal every other day. I was in the market for an SSD, just not an OCZ one, so I finally settled on a Kingston SSD, which was not even close to an OCZ as far as raw speed, but for $57 I have a 128gb SSD from a company that I've previously bought SSDs from, and any SSD will be faster than any mechanical drive, so for its purpose in my HTPC, I have much more peace of mind with my Kingston compared to any OCZ model (and that includes the newer Sandforce based models due to their issues coming out of sleep mode, which is what my HTPC does 90% of the time).
